Prevalence of minor congenital anomalies in newborns of diabetic mothers.

Minor congenital anomalies (MCA) were assessed in the offspring of 802 gestational diabetic mothers, 117 pre-gestational diabetic mothers, and 380 offspring born to normal mothers. The prevalence of infants with MCA ranged between 19.4% and 20.5% in the three groups without any significant difference between them. There was no correlation between the prevalence and type of MCA and the severity of the diabetic state. Neither was there any correlation between the prevalence or type of MCA and the appearance or type of major congenital anomalies.
